CYCLOMETEFL SPECIFICATION forming part of Letters Patent No. 555,659, dated March 8, 1896. Application tied'iiprn 22,1895. sel-a1 No. 546,729. (No moda.)

.To all whom, t may concern:

Be it known that I, GRANVILLE N terrine, of Jersey City, in the county of I-Iudson and State of New Jersey, have invented a new and Improved Cyclometer, of which the following is a full, clear, and exact description.

My invention relates to an improvement in a cyclometer especially adapted for application to bicycles, but it may be used in connec- Io tion with a wheel of any kind of vehicle.

The object of this invention is to provide a cyclometer so constructed that three hands may be used in connection therewith, one hand being adapted to indicate tenths of a mile and the second hand miles, while the third hand will indicate hundreds of miles; and a further object of this invention is to provide a means whereby by simply reversing one of the gears-the master-gear of the zo machine-the first hand named will indicate miles, the second hand ten miles for each point it registers with, and the third hand a thousand miles for each point with which it regtsters, thus imparting to the cyclometer a 2 5 registering capacity of ten thousand miles.

A further object of this invention is to construct a cyclometer in a simple, durable and economic manner, the change in the registering capacity being within the scope of any 3o person of ordinary intelligence.

Another object of the invention is to provide a trip for the cyclometer, adapted to be fastened to the wheel of the vehicle, and to so construct said trip that it may be iirmly and securely attached to a spoke of a wheel,

and especially to a spoke of a bicycle-wheel.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth,

and pointed out in the claims. n

Reference is to be had to the accompanying drawings, forming a part of this speciiication, in which similar characters of reference indicate corresponding parts in all the iigures.

4 5 Figure 1 is a perspective view of a cyclometer, illustrating its application to the Wheel of the bicycle. Fig. 2 is a plan view of the cyclometer with the dial removed, together with the hands. Fig. 3 is a horizontal sec- 5o tion through the cyclometer, illustrating the master gear or wheel in plan view. Fig. 4 is a plan view of the cyclometer, the masterwheel being removed. Fig. 5 is a section taken vertically through the cyclometer, practically on the line 5 5 of Fig. 2. Fig. 0 is a 55 detail side elevation of the trip adapted to be attached to the wheel of the machine or vehicle, and Fig. 7 is a view thereof at right angles to Fig. 6.

In carrying out the invention a casing A is 6o constructed preferably of circular form and this casing has attached to it in any suitable or approved manner an angular or substan tially L-shaped tube l5, comprising two members 10 and 11, the member 10 being longer 65 than the member 11. The casing is cut away, in a measure, where the member 10 of the angular tube connects with it, and this member contains aworm l2, the gear of which extends within the casing to a predetermined 7o extent, and at the outer end of the said worm a spur-wheel 13 is secured.

The member 11 of the angular tube B is provided at its outer end with a plug 14 and a spring 15, together with a second plug, 16, the outer plug being screwed or otherwise secured in the said member,while the inner plug is provided with a reduced section 17, which enters an annular groove 18 in the worm, it being understood that the worm-thread does 8o not extend the full length of the member 10, being formed upon a plain shaft 12"! The spring 15 serves in connection with the inner plug 16 to prevent the shaft 12 and consequently the worm 12 from being easilyturned, 8 5 thus preventing the revolution of the worm by objects, such as weeds and the like, turning the spur-wheel 13 as the vehicle progresses.

The casing A is provided upon its back with one or more posts 19, and these posts are at- 9o tached to a bracket 20, which is preferably secured to the fork 21, in which the wheel of the bicycle turns. Vithin the casing A a gear-wheel 22 is mounted to revolve, the said gear being secured upon a post 23, and the said post is journaled in the casing and at its outer end has a thumb-wheel 2/-1 or its equivalent secured thereto in order that said post may be revolved by hand, if desired. The

gear is fast on the post, and just above the loo gear a pinion 25 is formed upon or secured to the post, as shown in Figs. 3, 4, and 5. The

gear 22 is made to mesh with a pinion 2G, and said pinion is fast upon a stellated wheel 27, the said wheel being journaled in the easing at one side of its center. The stellated wheel consists preferably of a disk having a number of recesses in its periphery, as shown in Fig. 4f, and a spring detent or brake 28 is secured within the easing, being adapted to have constant bearing on the stellated wheel, the head of the brake being made to fit in the peripheral recesses of said wheel.

The master wheel or gear 2) is in the nature of a ring, and the teeth are produced upon the outer periphery, being adapted to engage with the worm or thread l2 on the aforesaid shaft l2, and through the medium of the said worm or thread the rin g-gear is revolved. rIhe ring-gear is preferably made of an outside diameter corresponding substantially to the inside diameter of the easing; and this ringgear is ,fitted upon one side with a single pin or stud 250, while upon the opposite side the .ring is provided with preferably ten pins or studs 3l, arranged at equal distances apart, and the positions of the pins 30 and 3l are such that when they 4are made to face inward and the ring-gear is rotated they will engage one after the other with the stellated wheel 27 to revolve the same against the detent 2S.

A cap 32 is made to substantially close one side of the casin g, being fitted over the master or ring wheel 29, and this cap is provided with a second opening through which the stud or spindle 253 attached to the central gear 22 passes, together with a predetermined portion of the pinion 25, attached to said stud or spindle, as illustrated `in Fig. A hand-train C is mounted on the said cap, and the said train consists of a small wheel 315, mounted to revolve on an arbor secured to the cap, the said wheel being provided with an attached pinion 34: and a second small wheel, 35,which is provided with a hub or sleeve 36, loosely mounted upon a reduced portion of the spindle 23 and above the cap. The gear 33 meshes with the spindle-pinion 25, being rotated thereby, and the gear or wheel 35, loosely mounted on the said spindle 23, is made to mesh with the pinion on the said wheel or gear 33, and in the said cap at one side a recess is ordinarily made in which a stellated wheel 36 is mounted to revolve, being rotated by contact with a pin 37, carried bythe wheel or gear 35, as shown in Fig. 2. A dial 38 is placed over the cap, being covered by a suitable bezel ?39 and crystal il). flhe dial may be marked off as desired. In the drawings it is shown as being marked in tens, reading from l0 to 100, and upon this dial a second dial 4l is made, corresponding substantially to the second-hand dial on a watch, and this second dial may be marked siniilarly to the large dial, and the spaces between the figures of both the large and the small dial maybe and preferably are marked off in similar manner to the spaces between the houriigures on a watch or clock.

A long hand l2 is secured directly to the main post or spindle 23 of the cyclometer, and corresponds to the minute-hand of a watch or clock. A second and shorter hand lf3, cor` responding to the hour-hand of a watch, is secured upon the sleeve 3G oi' the wheel 35 el' the train-gear C, while a still smaller hand -ll is made to rotate over the smaller or auxiliary dial ll, being carried by the upper stellated wheel 2) ln connection with the cyclometer a trip l) is employed, which consists of a block 15, preferably cylindrical in general contour, as shown in Fig. G, and this cylindrical block is provided with a cut or recess fl-6 in one of its faces, inclined in two directions, as is also shown in Fig. G. A :friction-roller el?, prel'ei ably covered by an elastic material is swiveled upon one end of this block, while a set-screw Ji-S is placed at the opposite end, extending through into the slot. The s poke if) of a bicycle-wheel, for example, is made to enter the slot 4G, and owing to the peculiar shape of this slot when the trip-block -l is secured on the spoke by adjusting the s( ew .41S to clamp the latter the friction-roller At7 will. be held horizontal, and each time the wheel makes a complete revolution the frictionwheel 47 will engage with the wheel lil of the cyelometer and move the said wheel a predetermined portion of a revolution.

In the operation of this device, when the ten pins 31 on the master or ring gear are made to face inward, at a predetermined number of revolutions of the wheel the shaft l2 will be turned sufli ciently to impart movement to the master-gear to such an extent as to bring one of the pins in engagement with the inner stellated gear, 27, and turn the said gear what maybe termed one tooth. In so doing the spindle 23 will be revolved and the long hand 42 will move one point on the dial, indicating one-tenth of a mile; and at the time the wheel has made one hundred revolutions, for example, the gear 33 of the handtrain will have been revolved to such an e;\- tent as to have imparted movement to the second whee'vl, S5, sufficiently to carry the short hand i3 to the figure l0, showing ten miles on the dial, and so o n, and when the short hand shall have reached the figure lOO the gear 35 on the hand-train willhave made a complete revolution, and will then move the upper stellated wheel, 3G, the distance of one tooth and indicate on the smaller or auxiliary dial 4l one point, oronehinidred miles. lVhen, however, the master-gear is turned with its single pin 30 inward, the record on the dial will be multiplied by ten. rlhe small. marks on the main dial will then indicate miles instead of tenths of a mile and the Iig ures hundreds of miles instead ol' simple miles, while the points on the auxiliary dial 4l will indicate thousands of miles each in,- stead of each indicating a hundred miles. ln this manner the capacity of the cyclometcr may be greatly increased, and yet the instru IOO IIO

ment may be made exceedingly light, simple and durable, and very small.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. In a cyclometer, a master-gear having trips differently arranged upon opposite faces, the gear being reversible, and a positive train of registering-gears operated by the trips of the master-gear, as and for the purpose set forth.

2. In a cyclometer, a ring master-gear having trip devices upon opposite faces, the said gear being reversible, and a positive train of registering-gears contained within the circle of the ring-gear, as and for the purpose specified.
